向量定比分点公式是向量空间一个基础关系式.它源于向量线性表达,受限条件少,结构简洁,应用宽泛、灵活,尤其公式对直线矢量的定向与定量描述,为架构数形转换平台创设便捷通道.当前中学数学教学对公式引入、讨论与应用关注不多,本文结合实例,介绍向量定比分点形式的结构特征及其所发挥的作用.1.向量定比分点形式的结构特征对于连接A,B两点直线上任意点P,向量定比分
Vector fixed score point formula is a basic vector space, which is derived from vector linear expression, limited conditions, simple structure, wide range of applications, flexible, especially the formula for linear vector orientation and quantitative description for the structure of digital transformation platform The current middle school mathematics teaching to the introduction of the formula, the discussion and application of little attention, this article combines examples to introduce the vector fixed point form of the structure and its role in the role of .1 vector fixed point form of the structural characteristics of Connect A, B two points on the line at any point P, vector set score
